The utility model relates to the technical field of computers, in particular to a
computer case heat dissipation device with a
water cooling function, and solves the problems that in the prior art, when facing a large amount of heat generated by a high-performance computer, the
air cooling technology is often out of effort, and the heat dissipation effect is limited. Especially in a closed or high-temperature environment, the heat dissipation effect of an
air cooling technology is greatly reduced, and the heat dissipation requirement of a modern high-performance computer is difficult to meet. A
computer case heat dissipation device with a
water cooling function comprises a case and a mounting plate. An opening is formed in one side of the case, the mounting plate is arranged at the position of the opening, and one side of the mounting plate is detachably connected with the side wall of the case; a plurality of mounting grooves are formed in one side of the mounting plate, and
semiconductor refrigeration plates are connected into the mounting grooves. The
computer case is reasonable in structure, the interior of the computer case can be conveniently and rapidly cooled through
cold air, the defect of
air cooling is overcome, and cooling quality and efficiency are improved by combining
refrigeration.
